3 . When places are well-known and popular— historical and modern alike— we might take it for granted that they’ll be around forever. But sadly, many of the world’s best known and culturally significant landmarks are in trouble.

Mount Kilimanjaro’s peak

This mountain, one of the Seven Summits, proves that even giants can fall to climate change due to the vast amounts of greenhouse gases in the atmosphere. While the mountain itself, located in Tanzania, isn’t in danger at present, its iconic snow cap might disappear—and shockingly soon. Research found that the snow cap had lost 85% of the total area of its ice fields between 1912 and 2007, and the remaining ice could be history as early as 2030.

Machu Picchu

Located in southern Peru, Machu Picchu is the remains of a huge stone castle that was built during the 15th century. These unbelievable Incan ruins are widely considered one of the must-see spots in South America. However, the site has been a victim of over-tourism, seeing the harmful effects of the crowds it gets as they wear down the structures. In addition, the area surrounding Machu Picchu has seen rapid development of the cities, as well as mudslides and fires, in recent years, leading UNESCO to work for its protection.

Everglades National Park

This stunning Floridian wildlife reserve has sadly found itself fighting for its life in recent years. As ‘the largest subtropical wilderness reserve’ in North America, according to UNESCO, it’s been a beloved travel destination for American citizens for decades, but the damage of time and human activity have not been kind to it. Its survival first came into question after it was destroyed by Hurricane Andrew in 1993. But it’s human influence that has become the primary threat, as water flow to the site has decreased and the impacts of pollution have increased, resulting in harmful algal blooms (赤潮). Its vast, diverse wildlife is more threatened than ever before.

1. Which problem does Mount Kilimanjaro face?

A．Global warming	B．City development.
C．Over-tourism	D．Ice pollution.

2. What do these three places have in common?

A．They are the impacts of pollution and mudslides.

B．They are destroyed severely due to over-tourism.

C．They are famous but affected by human activities.

D．They are considered as victims of global warming.

3. What is threatened by human activity in Everglades National Park?

A．Lack of popularity.	B．Hurricane Andrew.
C．Algal blooms.	D．Diverse wildlife.

4 . Money Daniels spends several hours every week cleaning up cans and bottles in the rivers near his home with other teen environmentalists in Chattanooga, TN. Together, they have collected more than 1 ton of aluminum cans, nearly 1,000 cans a week for a year. In January, he co-founded a club called the Cleanup Kids with his best friend. The project’s mission: to encourage kids to pick up 1 million pounds of trash across the globe before the end of the year.

Daniels says he first developed a passion for wildlife when he was 3. “As far back as I can remember, I’ve always loved animals,” Daniels says. Marine life especially interests him. When he began discovering trash on walks along the river with his family, he immediately thought of his favorite sea creatures.

His mission now is saving the earth’s rivers, which he points out are even more polluted than the world’s oceans. “Eighty percent of the ocean’s trash comes from rivers,” he says. In 2019, he adopted the name Conservation Kid on Instagram, and started posting about things like how something as simple as a deserted face mask can entangle (缠住), choke, and kill turtles, birds, and fish. Mask waste has increased an estimated 9,000% since the pandemic(疫情) began.

Although he mostly speaks to other teens, Daniels has found that adults are often persuaded by his argument that cleaning up, recycling, and ridding plastic ought to be a selfish act for humanity: when plastics break down, they can wind up in our drinking water. He has met with the mayor of his city, and his experiences speaking with influential grownups has convinced him that adults can change their habits.

But, in truth, the burden to save the planet has landed on children like him. “Kids may be a small percent of the population, but we’re 100% of the future,” he says. “And we can save the world.”

1. What led to the birth of Daniel’s project?

A．The inspiration from his best friend.

B．The goal to make a role model for kids.

C．The concern for the ocean life.

D．The idea of other teen environmentalists.

2. Which can be inferred from paragraph 3?

A．The ocean’s trash has grown rapidly.

B．The river pollution requires less attention.

C．Many animals are infected in the pandemic.

D．River waste contributes most to the ocean’s trash.

3. Which of the following can best describe Money Daniels?

A．Optimistic and creative.

B．Caring and responsible.

C．Considerate and generous.

D．Courageous and devoted.

4. What is the passage mainly about?

A．Grownups’ selfish behaviors for humanity.

B．A teenager’s contributions to saving the waters.

C．A youngster’s responsibility to protect the world.

D．Teen environmentalists’ efforts to clean the oceans.

5 . Around the world, people are realizing the significant problems caused by plastic waste. In the last 65 years, we have become increasingly dependent on plastic. It’s easy to understand why: it’s cheap to produce, light — therefore easy and cheap to transport — and incredibly strong and durable.     1    

One popular solution to the problem is to prohibit single use plastics. In the British supermarkets, shoppers are encouraged to make more environmentally-friendly choices in packing and transporting their food.     2     Some governments have even promised to ban the use of single-use plastic altogether by the not-too-distant future.

However, such plans may not be beneficial to eliminate (消除) the use of single-use plastic altogether.     3     This is not just because of its low cost. It’s also because infection and cross-contamination (交叉感染) are minimized. Plastic packaging is also crucial in the food industry. It ensures that food is safe for consumers.

Another issue is that alternative materials to plastic are often more environmentally harmful than plastic. Take paper bags, for example.     4     The process requires cutting trees, the emission of greenhouse gases and the production of poisonous chemical waste. Even more pollution is created when paper bags break down.

Clearly there is a need to reduce plastic waste and its impact on the environment.     5     Industries that rely on single-use plastics for people’s health and safety must be considered. Moreover, alternative materials must be evaluated strictly regarding their own environmental impact.

A．But it’s these advantages that also make it so harmful.

B．They are very fragile and rarely reusable, unlike plastic.

C．One of the fields where single-use plastic has a vital role is medicine.

D．However, simply banning their single use may not be the best option.

E．It also boosts the local economy and save costs in managing littering and waste.

F．Bans on single-use plastic items like drinking straws are also coming into place.

G．According to a research, they require four times more energy when produced than a plastic bag.
